provide a safety valve which cannot be accide'ntallyopened and w llCll cannot bereadily Another object of the invention is to provide a gas valve in which definite operations must be performed before the valve maybe opened.

' A further object of the invention is to progvide a gas valve having an annularmember normally preventing opening of the valve,

' Another object of the invention is to provide a valve having an annular member is closed and the valve prevent reo'peningof the valve.

As shown in Fig. 1 the valve comprises a body '1 having an inlet 2 v and an outlet 3. The valve is provided with the usual rotating :portiont and the body 1 is provided with two shown more particularly in Fig. 3, extending up about the rotating member Y The rotating'membe'rf l is provided with apin'7 adapted to be moved-by turning the handle 8 when the valveis opened. An annular member 9'is provided as shown in Fig.3, having a small lug 10 on oneside and a wide lug 11 on the oppositeside extending between the lugs 5; and 6 This annular and when the handle 8 is closed and the August 31', 1927..

member9 is provided with an additional this position, as shown in Fig. 3, the valve cannot be opened as the pin 7 engages the lug 5 when the handle 8 is turned in one direction is turned in the oppo- 7 engages the annular member 6 which prevents the valve from being turned- To open the valve it is necessary to raisethe annular member 9 manually so that the pin 7 is beneath the annular member 9. At this time the valvemay be readily opened asindicat-ed in Fig. 2 and the member 9 remains in the position shown in Fig. 2 as long as the valve remainsopen. As the valve isclosed the pin 7 is moved beneath theznotch l2=which allows the member 9 to fall by gravity thus preventing the valve from being opened until the member 9 is again raised. This valve is arranged to prevent the valve from being accidentally opened which sometimes occurs when a per son is working around the range and it also site direction the pin eliminates the possibility of a child opening the valve as this is usually done by young children who do not understand the dangers of escaping gas and are therefore too young to understand the two operations necessary to open the valve. One of the particular features of the invention is involved in the construction whereby the closing of the valve automatically locks the valve .from further openin without attention from the operator. This is accomplished by means of the annular member 9 which drops by gravity as soon as the valve member 9 is made with suflicient clearances to freely fall by gravity as soon as the valve is closed.

From the foregoing description it becomes evident that the device is very simple'and efficient in operation, will not easily get out of order, is composed of few parts and is of Having thus fully described my invention,

its utility and mode of operation, what I claim and desire to secure by Letters Patent ofthe United States is- 1. In a valve for gas ranges, a valve body limit turning movement of the valve memher, an annular memberfhaving notches fitting over the guide lugs, one notch being greater in width than the width of the companion lug and providing a space intowhioh the said pin may extend when the valve is closed, the arrangement being, such that when the annular member is moved upwardly on theguide lugs above the pin the valve 7 may be opened.

2'. In a valve for gas ranges, a valve body having a pair of upwardly extending arcuate guide lugs, a valve member rotatably mountedin the body, a pin carried by the valve member and extending between the guide lugs to limit turningmovement of the valve member, an annular member slidable verti-r cally on the guide lugs, said lugs preventing rotation of the annular member in relation to the valvebody, the annular member having a notch into which the pin extends when the valve is closed, the arrangement beingsuch that when the annular? member is moved upwardly on the guide lugs "above the pin the valve may be opened. i i y In testimony whereof I sign this speeification.
